HAT-IRONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 273,670, dated March 6, 1883.

Application filed December 13, 1882.

To all whom it may concern.-

Be it known that we, ALBERT DE LASKI and EDGAR SHAW, both of Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Hat-Ironing Machines, of which the following is a specification.

This invention is an improvement on that described in Letters Patent of the United States, No. 246,297, granted August 30, 1881, to A. De Laski, and involves the employment of an oval lathe to support the hat-block and an iron heated by gas and air under pressure, said iron being movable, so as to act on any part of the hat-body.

The present invention has for its object to enable the iron to be controlled by the operator instead of being automatically operated, as in said patented invention, and to provide certain improvements relating to the means for supporting and operating the iron, to the construction of the iron, and to the means for supplying air, under pressure, to the iron.

To these ends our invention consists in theimprovements hereinafter described and claimed.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation, partly in section, of a hatironing machine embodying our invention. Figs. 2 to 14, inclusive, represent views of details.

The same letters of reference indicate the same parts in all the figures.

In the drawings, A represents the frame of the machine, supporting the operating portions hereinafter described.

B represents the driving-shaft, which is rotated by abelt, and has at its inner end a bevelpinion, B meshing with a bevel-wheel, B on the inclined'shat't B, said shaft giving motion to the oval lathe, on which the hat-block O is supported. The oval lathe is constructed, excepting as to certain minor details, in the manner described and shown in the above-named Letters Patent, the top plate, P, of said lathe, on which the hat-block rests, being rotated in an oval path, which is adjustable to adapt it to conform in shape to the crown of the hat to be ironed. The novelty in the oval lathe consists in locating'the adjusting-screw 10, which (X0 model.)

plate Lof said lathe below the inclined portion A of the frame A instead of above the same, as described in the former patent, so that said screw can by no possibility interfere with the cord encircling the hat-body and depending therefrom. The car 13 of the ring L, that receives the screw 10, is detachably secured to said ring by means of a screw, 11, and projects through a slot in the inclined portion A The top plate, P, has a series'of spurs, a, adapted to enter the base of the hatblock, and a central chuck or spindle, I), having longitudinal wings or flanges I) b. The hat-block has a corresponding socket adapted to fit said chuck and its flanges, the latter preventing the block from rotating on the chuck.

d represents the hat-iron, which has two or more operating or ironing sides, as hereinafter described, and is provided at one end with a closed trunnion, d, and at its opposite end with an open or tubular trunnion, d Said trunnions are adapted to rotate freely in bearings formed at the outer end of a jointed supporting-frame, c, composed of a primary frame, 2, journaled in an elongated bearing,f, on the frame A, and a secondary frame, 4, pivoted to the primary frame at 5 5, and having bearings 6 G'for the trunnious of the iron. The primary frame is composed of the transverse arbor or rock-shaftjournaled in the bearingf, and two arms rigidly attached to said arbor, one of said arms being extended to form a handle, it, and the secondary frame is composed of two side pieces rigidly connected by transverse braces 8, as shown in Fig. 7. It will be observed that the described construction of the supporting-frame 0 enables the iron to have what may be termed a parallel movement-that is to say, it is free to move laterally in any desired direction-so as to move progressively from the top of the crown to the base of the body of the hat; but its axis is always parallel with a. given line, and cannot be inclined or tipped longitudinally from such parallelism, the supporting-frame being so constructed and supported as to be incapable of any torsional movement at its outer end. This manner of supporting the iron enables the operator to control it perfectly and present it to the best advantage to the hat. The

adjusts the position of the grooved guide- I closed trunnion d of the iron has a knob or handle, it, and the frame 6 has a handle, h previously described, said handles h and h being grasped by the hands of the operator during the ironing operation.

j represents an arm rigidly attached to the outer part, 4, of the frame, and supportingat its outer end a block or boss, K, projecting into the outer end of the tubular trunnion at, said boss fitting loosely in said trunnion, so that the latter can rotate freely on the boss.

m n represent respectively gas and air pipes passing through and secured rigidly to the boss K and projecting into the tubular trunnion 61?. The gas-pipe m terminates in a burner at its inner end, and the air-pipen isextended farther inwardly than the gas-pipe, and is offset at its end so that its discharge-orifice is directly in line with the burner.

0 represents acollar connecting the pipes m a near their inner ends, said collar fitting' loosely in the trunnion d The pipes on n are connected respectively by flexible tubes m n to a source of gas-supply and to the chamber 0 of an air-pump supported by the frame A and operated by a connection with the drivingshaft B, as hereinafter described. The iron cl has an internal chamber, 1", corresponding to the external form of the iron, and into said chamber projects a tubular flue, s, forming a continuation of the trunnion d Said flue is centrally located in the chamber 1', and is entirely surrounded by said chamber, so that an intervening space exists between the flue and each of. the operating sides of the iron, said space preventing the flame projected by the gas and air pipes into the flue s from coming in contact with the walls of the chamber 1 and overheating the operating sides of the iron. The inner end of the flue .5 opens into the chamber 1', as seen in Fig.8. In the trunnion 01 and close to the end of the iron, are orifices t for the admission of atmospheric air into the flue s in advance of the gas-burner.

n n represent orifices or vents in the end of the iron for the escape of the heated air and products of combustion from the iron. Said vents are arranged in close proximity to the orifices 15, so that a portion of the hot air escaping from the iron will re-enter the iron through the orifices t, as indicated by the arrows in Fig. 8.

The iron at is preferably triangular in crosssection, having therefore three operating sides. Oneof said sides, d*,is concaved longitudinally of the iron, as shown in the Figs. 7, 8, and 9,

and is thereby adapted to fit the curvature of the sides or body of the hat. Another side, 01 is concaved laterally, as shown in Figs. 1 and 9, so as to fit the curve of the crown where the latter joins the body of the hat, as clearly shown in Fig. 1. The third side, d, is flat laterally andlongitudinally, and is used or not, as the operator may, desire.

The air-pump that supplies the air under pressure to the chamber 11, and from the latter to the iron (I, is composed of a cylinder, u, having a flange, u, that is bolted to a horizontal plate, A", rigidly affixed to the frame A, said plate having an orifice, A, (see Fig. 4,) receiving the cylinder u. The lower end of the cylinder u is open, and the upper end has a head, 20 having an opening, a and a downwardlyclosing valve, a, secured to the upper side of said head.

a represents athreaded flange on the upper side of the head 10 To said flange the chamber 19 is screwed, the latter being internally threaded at its lower end or mouth. The chamber 19 is thus made easily removable, so that the valve a can be conveniently reached for repairs, &c.

, 3/ represents the valved piston of the airpump. The rod y of said piston is guided at its lower end in a yoke, 11*, rigidly attached to the frame A, and to said rod is pivoted a short rod, 3 attached to an eccentric, 1 on the driving-shaft B. The rotation of the drivingshaft causes the eccentric to reciprocate the piston, and thus force air into the chamber 10. It will be seen, therefore, that one and the same driving-shaft rotates the hat-block and operates the air-pump. The chamberp is provided with a spring safety-valve, p (Shown in section in Fig. 3.)-

We do not limit ourselves to the improvements in the iron-via, the arrangement of the due s and the concave sides d and (1 in an iron adapted for use only in an ironing-machinefor it is obvious that said improvements may be applied to a hand-operated iron.

1" represents a forked standard, attached to the frame A and adapted to support the crossbar or brace 8 of the frame e, and thus support the iron in a raised position away from the hat block. The standard 1" has a backward curvature, as shown, which makes it somewhat yielding or springy, so that when the cross-bar8 is dropped suddenly upon the standard the shock or jar caused thereby will be somewhat relieved and breakage will beavoided.

We have shown in Figs. 9" and 9 a triangular iron havingin one of its sides a concavity, 9, including only apart ofthe length and width of the side in which it is formed, and having a different angle in the cross-section of the iron from the other portion of the side of the iron in which the concavity is formed. The adjoining side, 10, of the iron is flat and partly cut away by the concavity 9, so that theintersection of said concaved and fiat sides forms a longitudinally-concave angle which is acute at all points. The flat side 10 is thus adapted to press the brim of a hat, the concave acute angle being adapted to fit closely against the hat-body under the incircling cord. When the flat side 10 rests on the brim of a hat the concave side 9, being at an acute angle with said flat side, affords a space between the side of the hat-body and the side of the iron adjacent thereto, so that the operator can observe the concave edge of the operating side 10. This feature-via, a flat side having a concave acute-an gled edge formed by the intersection with said flat side of a concave side at an acute IIO angle with the fiat side-may be used in ahandoperated iron. The axis of the oval lathe is inclined, as shown in Fig. 1, so that the crown and sides of the hat-body are both about equally inclined from a vertical line, and will therefore both receive about the same degree of pressure from the iron. It will be seen that thejointed frame 6 permits the entire weight of the iron to bear upon theinclined sides and crown of the hat, so that the iron requires no pressure against the hat by the operator, who simply has to move the iron back and forth by means of the handle it on the jointed frame.

We are aware that an iron having aflat and a concave side forming an acute angle has been before used. Hence we do not claim the same, broadly.
